Landing legs, even in their folded position, will give some aerodynamic resistance to roll.

...and extending them should slow any roll, just like figure skater extending the arms.

Quite possibly. The question, though, is how the roll developed in the first place.

Musk: will next attempt recovery on 4th F9 v1.1 launch, of CRS-3. That vehicle may also have landing legs. #falcon9

Wont they need to do more Grasshopper flights first to get the landing system down?  There is a big difference between landing in the middle of the ocean and an exact spot on land.

Adding landing legs does not mean they will land it on land - they might just add them to test the shape of the stage, the diffirent center of gravity. I doubt they'll do full boostback - need to build a landing area for that first anyway.
So, same flight as today, just with added legs / leg deployment just above the ocean is a possibility.


Heh.  All they need to do is lay out a concrete pad.  And since the stage is empty at landing, it doesn't need to be engineered to take a lot of weight.

How much you want to bet we will see some concrete truck activity in the next few months?

Musk: working with Air Force and FAA on identifying landing sites for F9 1st stage, looking at eastern tip of Cape Canaveral. #falcon9

Looks like an old pad? What pad was this?

Musk: still working on 3rd launch site, "quite likely" to be Texas but not resolved yet. #falcon9

Musk: Also pursuing LC-39A at KSC for NASA (cargo and crew). Current Cape launch site would be used for other customers. #falcon9

As someone else suggested, perhaps the stage is spin stabilised during descent to keep attitude when engines are not lit. Using three engines give capability to create quite fast spin.. :P

That will be spectacular to see.

Anyway congratulations to Space X on this successful launch.

Musk: goal is to attempt 1st stage recovery on all future CRS launches and many others; next two (w/out recovery) more of an anomaly.

Musk: if things go "super well", could refly a Falcon 9 1st stage by the end of next year.

They must feel really good about 1st stage re-entry performance if they're already looking for a landing pad. I wonder how pin-point close it came to where they expected it to be?
